| [study on the coinfection of three tick-borne infectious diseases in china using polymerase chain reaction method]. | to study the existence of ehrluichiosis, lyme disease and tick-borne spotted fever coinfection in some areas in china. | 2005 | 15921584 |
| [detection of north-asia tick-borne spotted fever in ticks and rodents along the heilongjiang river-side by restriction fragment length polymorphism of pcr products]. | in order to elucidate the natural foci of north-asia tick-borne spotted fever along the bank of heilongjiang river, we used pcr/rflp to detect spotted fever group rickettsiae in ticks and rodents. the results showed that the wild samples of dermacentor silvarum, haemaphysalis concinna and apodemus agrarius, microtus fortis, clethrionomys rufocanus and ondatra zibethica were all positive with amplification, but typhus rickettsiae, tsutsugamushi fever rickettsiae and q fever rickettsiae were all n ... | 1997 | 9812471 |
| genotypic identification of three new strains of spotted fever group rickettsiae isolated in china. | polymerase chain reaction (pcr) and restriction endonuclease fragment length polymorphism (rflp) analysis were used to characterize the genotypic diversity of three isolates of spotted fever group (sfg) rickettsiae isolated from ticks in china. a primer pair designed from dna sequence encoding 190 k protein antigen of r. rickettsii and genomic dnas obtained from the isolates were used in pcr. the pcr products were cleaved with restriction endonucleases psti and rsai, and the digestion patterns w ... | 1996 | 9014012 |
| [survey on tick vectors of lyme disease spirochetes in china]. | since 1987 we have been studying on lyme disease in china. there were 71 isolates of borrelia burgdorferi recovered from six species of ticks including ixodes persulcatus, ixodes granulatus, ixodes rangtangensis, haemaphysalis concinna. haemaphysalis bispinosa and haemaphysalis longicornis, and 55 isolates from ixodes persulcatus collected from heilongjiang, jilin, liaoning, nei-monggol, hebei and xinjiang region (province). ixodes persulcarus is the dominant species accounted for more than 80% ... | 1992 | 1300244 |
| [investigation on the vectors of borrella burgdorferi and on the identification of the isolates along china-russia border in eastern heilongjiang province, china]. | to explore the fact that the east border of heilongjiang had been a lyme disease natural focus,we investigated the species and distribution of ticks and isolated bacteria from ticks and identified genomic species of borrelia burdorferi sensu lato. this study provided evidence for prevention and control of lyme disease. | 2007 | 17575937 |
